Hi to yal. Just bought an AC 200 tractor on sunday. Had it running today moving snow out of my driveway. Tractor was running great and had great power. Got off tractor to run in side. Left tractor idiling. Got back on tractor started moving forward. Had the blade up and the tractor just shut off. It did not spit or sputer like it was losing fuel psi. It simply just shutt off like i had reached down and pushed the fuel pump shutt off cable in. Hit the start button and the tractor fired right up. It did not miss or chug like there was are in the fuel. Does any have any suggestions. Or has any one seen this before. Any help is appreciated. Thanks

I take it it's a diesel because you said "...fuel shutoff cable...." What temperatures are you operating in? If it's below freezing, have you changed your fuel filter's recently? Are you usinga fuel treatment that will disprse the water in the fuel tank? Most shutdowns are caused by icing on the filters and/ or in the tank bottom from water contaminated fuels. I use Power Service White or Stanadyne fuel treatments in the winter to help disperse the water The the fuel filter can take it out. it may freeze on the filter but you can remove the filter and replace it (or thaw it if you are desparate), but there's not much you can do short of putting the tractor in a warm place if the tank outlet freezes.

I have had water freeze up in the water separator. I also recommend changing filters BEFORE the cold weather gets here as a preventative. A used filter will ice up quicker than one that's fresh.

If the temps get below about 10F and you are using a summer fuel, you could have some gelling of the fuel. I ususually use #1 diesel in at one part #1 to two parts #2 as a precaution for gelling but I have never had that happen at least down to -20F...yet.. If it does occur, it will look like yellowish mucus in the tank and if it congeals on a filter or a water separator, it will look like a yellowish wax.It's actually is a parafin that occurs in #2 fuel. #1 is #2 with the parafins removed. There is a product called Diesel 911 that's suppose to deal with this problem by disolving the parafin . I have never had a need to try it.

Water is the most common contaminat in diesel fuel and you can minimize water condensate in the tank by keeping the tank full of fuel.

That's a long answer to your post but I hope it helps you.

Thanks for the info. I think i found the problem. It looks like there was supposed to be a clamp on the fuel kill cable. The clamp was missing letting the cable push forward killing the fuel. Secured the fuel kill cable and havent had a problem since.
